3 Claims.

This invention relates to a dispenser for mater-ials of different consistencies, and from which it may be dispensed with facility in desired quantity.

Different kinds of dispensers had been used before which mainly consisted of two cylinders one of which could be screwed into the other thereby pressing out the content through an orifice. These kinds of dispensers could not be used for all materials namely fluid, semi-fluid and such of thick consistency and besides that most of them had an open orifice which made it possible that the material dried out or got spoiled; Other dispensers have also been used which contained merely one cylinder and a plunger fitting in the cylinder was forced down by a screw and thereby pressing the material out through a steadily open orifice arranged near the upper end of the dispenser. Thus this kind of dispenser could be used only for a limited number of materials and the steadily open orifice dried out the material very quickly.

It is, therefore, the primary object of the present invention to provide a universal dispenser which can be used for material of all consistencies-that means for fiuid, semi-fluid and even thick consistency.

A further object of the present invention is to provide a dispenser with an orifice which has means for airtight close-up of said orifice.

Still another object of the invention is to provide a universal device of the above character which is very economical in manufacture, strong and durable in construction and will efficiently perform the function for which the same is devised.

A still further object of the invention is to provide a dispenser with means for providing pressure in the cylinder upon the goods, which means work independently from the closing means of the orifice.

Yet another object of the invention is to provide a dispenser in which the pressure means make the closing means of the orifice still tighter.-

Other objects of this invention will be apparent from the following description of the dispenser which is illustrated by way of example in the accompanying drawing, of which:

Figure 1 is a vertical section of the dispenser along line I-I of Figure 3;

Figure 2 is a vertical section of the dispenser along line 2-2 of Figure 3; and

Figure 3 is a plan view of the device.

The dispenser consists of a cylinder I with an orifice 2 at its bottom 3, which orifice 2 is conically shaped in order to serve as a valve-seat and to receive'the conically shaped end 4 of a rod 5 extending through the cover 6 of the cylinder I which cover 6 is screwed to the cylinder I by means of a thread I adapted on top of the outside of cylinder I. The bottom 3 of cylinder I is equipped integrally with an annular ring 8 to provide a standing base for the dispenser. A piston 9 glides along the rod 5 up and down by arranging a center opening In, which piston 9 is connected with two rods I I extending through holes I2 of the cover 6 and closing bridge-like to one piece. The top of the bridge part of the rods II has one or two grooves l3 to provide a rest for the fingers when using the dispenser.

The cover 6 is equipped with a vertically extendingforked part I4 the top of which is arranged as pivot I4 for a double armed lever I5 extending to the center of the dispenser. The arm I6 of lever I5 extending to the center 'of the dispenser ends in a slot I'I arranged near the top of the rod 5, whereas the arm I B of lever I5 extending away from the center of the dispenser is flattened to provide a larger surface for the finger actuating the dispenser. A spring I9 is adapted on rod 5, one end of which spring I9 presses against the cover 6 and the other against a spring plate 20 fixedly arranged on the rod 5.

The outside of the orifice 2 of the bottom 2 can be equipped with threaded outer surface 2| and a cup 22 screwed on'that orifice 2, thereby closing up the orifice for filling purposes only.

Depending on what kind of material the dispenser is to be filled with the filling can take place either through the orifice 2'or through the top by unscrewing the cover 6 from cylinder I and removing piston 9 and rod 5 with cone A from the cylinder I. In the first way no use has to be made of the cup 22, whereas filling the second mentioned way the cup 22 has to be attached first, to be removed again, when the filling is completed and the cover 6 is screwed to cylinder I again. In this position the contact of the container alone will press the cone 4 of rod 5 on the seat 2 but can be supported by a spring 19 and this will be sufiicient to close up the container entirely. When liquid or semi-liquid materials are used the piston 9 and the rods II seem not necessary at all. Since the orifice is arranged at the bottom the material will just flow out by pressing down arm I8 of lever I5 against action of the spring I9, if any spring is provided. By releasing the pressure on arm I8 the spring I9 returns the cone 4 immediately on its seat and closes the cylinder I air tight. In

order to achieve this, a tightening ring can be provided in the cover 6 where the rod 5 extends to the outside.

Whereas it is possible to fill up the cylinder l with liquid or semi-liquid material through the orifice 2 of the bottom of the cylinder l by lifting the valve 6, the filling of the cylinder 1 with material of thick consistency takes place advantageously fromthe top, after; removing, the.

stem 5, the valve 4; thepiston 9., and the cover: 6-3 10 combinationiof:a-container -for said material with Since the orifice 2 is open after removal of the stem 5 with the valve 4 a special closing cup,

22 is provided in order to close up,the..,orifice. 1,.

during the filling period, but which-cup '22:;can;

be removed after inserting again the valve 4. In this case the dispensing is achievedby, tak.-; ing two steps.
